Make my app launch when secret code entered?

Question

How would I make my app launch when a secret code, such as *#*#12345#*#* is entered into the dialer?

I couldn\'t find a solution in the Android docs.

Insted broadcast reciever maybe you should register to proper activity intent. For example Intent.ACTION_CALL looks promessing. Problem is how to filter intents to recive only this one specyfic number. I suspect that it would look like this (I'm gesing based on what I've found in documentation):

Look here and here. Use LogCat to see what exacly intent contatins then you can filter this properly.
